[TxMt] svn hangs

I run a script to update bundles. At the moment it seems to hang trying to
update Rails. Anybody know what's happening and what to do about it?
Everything seems fine until near the end of the process, when I see:
Fetching external item into
'Bundles/Rails.tmbundle/Support/plugins/textmate_footnotes'
External at revision 121.
Fetching external item into 'Bundles/Rails.tmbundle/Support/plugins/engines'
... and there it sits.
The script is
#!/bin/sh
cd /Library/Application\ Support/TextMate/
/usr/local/bin/svn up
osascript -e '
and has been working for months.
I tried exiting terminal, which ended the script but left "engines" locked.
svn cleanup resolved that.
